“I’m kind of done with it all. I’ve washed my hands with it. I would’ve thought that he was the least likely person to stray and I said that to Yvonne. He’s not the person I thought he was.”

Former left-back McKinlay – who now works as a scout for Celtic – played for Scotland at Euro ’96 and the World Cup in France in 1998, and was part of the Hoops team who won the Scottish Cup in 1995 under Tommy Burns.

Yvonne, 52, told how she initially forgave her husband of 28 years – whose first name is Thomas – after he swore his relationship with Porteous lasted only a few weeks.

However, she claims she eventually sent him packing after it emerged he’d been close to Porteous for a decade.

Yvonne said: “This has been absolutely devastating. Out of anybody, I would’ve put my life on it that my husband would never, ever stray. I thought we’d be together forever. He wasn’t a flash stereotypical footballer. He doesn’t even drink.

“To find out he’d been leading a double life for 10 years was so hurtful. All those lies and deceit makes me feel I just never really knew him.”

Yvonne’s suspicions were first aroused when she received an anonymous email in January 2016 saying McKinlay was cheating on her – but he denied it. She claimed Porteous told her about their affair when the pair met in a pub in May 2016.

Yvonne says McKinlay begged for forgiveness and insisted his relationship with Porteous – who works as a waitress at Celtic Park on match days – had been a fling which lasted about two months.

But Yvonne, of East Kilbride, caught McKinlay visiting Porteous’ flat in Renfrew five months later and the full extent of the relationship unfolded.

Yvonne claimed she was left shattered when Porteous read out X-rated texts she’d received from McKinlay to prove they were a couple.

Yvonne said: “The first time I met Porteous was when she accosted me in a pub toilet. I didn’t know who she was but she said she was having an affair with Thomas.

“He told me that she was a friend and they’d had a wee fling. He said it never felt right and it was the biggest mistake of his life.

“Thomas insisted Porteous meant absolutely nothing to him, it had only been a couple of months and I wanted to believe him.

"I thought we could work things out and was thinking maybe Thomas was going through a mid-life crisis. That was in May. But in October he called me to say he was working late and something just made me drive over to where Porteous stayed.

“When I arrived, Thomas’ car was there. He just did a runner but Porteous told me their relationship had started 10 years ago. She read out some texts between them and some were vulgar.

“I couldn’t imagine my husband would even write things like that. I was numb. She seemed to enjoy rubbing my face in it. As I left her flat, she shouted, ‘Maybe I should move into your big house and we could all live together’ – and laughed. I said, ‘I don’t find that funny’ and she said ‘I’m sorry’.”

Yvonne and McKinlay married in Glasgow in June 1990. The couple suffered agony in 1994 with the death of their nine-month-old son Jordan from a rare genetic disorder.

McKinlay – who played 90 times for boyhood heroes Celtic after a £350,000 move from Hearts in the same year – has a tattoo of Jordan on his left arm. Yvonne said that McKinlay has not been in touch with their daughter Nicole, 26, or son Conran, 20, since his double life was exposed.

Nicole gave birth to his first grandchild Zak last July. Yvonne added: “Thomas portrayed himself as a family man so to behave this way has been such a shock. Everyone who knows us is stunned.

"We’ve had no contact with him since October. It makes things more devastating because he’s not fought to try and keep in touch with his kids. Marriages break down but to not try and stay in your kids’ lives?

“They’re angry at how their dad has behaved but Thomas needs to work that one out. I can tell you that if I’d done something wrong and hurt my children, I would fight tooth and nail to rebuild a relationship with them.

“He’s got a wee grandson – but nothing. I look at Zak and think, ‘How can he miss out on this?’It was Nicole’s birthday last week and he never sent her a text or anything.”

Yvonne has not filed for divorce but insists the marriage is over.

She said: “I’ve kept my dignity and I’ve not caused him any grief but it’s galling to think everyone still thinks he is a hero and a family man. The public need to realise he’s not the lovely person they think.”

Porteous – who brazenly tweeted last April about going to watch “my handsome play” – denies Yvonne’s claim she and McKinlay had a 10-year affair.

She said: “That’s rubbish. We’ve known each other that long but no, we didn’t have a relationship that length of time. He did tell me he loved me a long time ago but I never went with him. We didn’t get together until about 18 months ago.

“We hadn’t spoken for a long time because of all the issues with his family. I’d said I didn’t even want to be his friend. I didn’t want to get dragged into all this but it happened anyway, just for being his friend.”

McKinlay failed to respond to numerous requests for a comment. Celtic refused to comment.
